Anita Blake is an "animator" in this the 17th book in the vampire hunter series. An animator is someone who reanimates dead people or vampires or weretigers or whatever in order to interrogate them for legal purposes. She is called to Las Vegas to help with an investigation of the grisly murder of several Las Vegas cops after being sent the head of one of them.
I didn't get very far into this book. The language was absolutely awful with the f-word and other profanities on every page and lots of sexual references. After reading several reviews, I found that the book isn't very well written either. Not very many people liked it, even those who were fans of her earlier books. Definitely one to avoid. Rated R. Maybe even NC-17 but I didn't read enough of it to find out.
